Description

FIELD OF THE INVENTION

The present invention relates to an energy verifier and, more particularly, to an energy verifier that can measure electrical energy, water, gas, diesel, combustibles, etc.

One of the main characteristics which is lacking in existing equipment is its capacity to connect to a network and the inclusion like a module within measurement systems of multiple points. That is to say, include the same equipment hardware within a single cabinet with other measuring devices that are in charge of measuring a number of groups of energy users (multi-point concept).

Any equipment developed in Mexico of similar characteristics does not exist.

The design is composed of a modular form and includes capacities for network connection and the inclusion like a module within multi-point measurement systems. The modular components of the design are: three-phase measurement machine, interface and peripherals for LCD screen, high precision real-time clock, external non-volatile memory bank (flash), energy fault detector to backup vital information for the meter, interface and peripherals for navigation buttons, interface and peripherals for leds RGB indicators of events and status, UART communications interface, RS 485 communication bus, optical communication interface for ANSI C12.18 protocol, communications interface to extend to external modules of remote access like Ethernet, GPRS, radio frequency, Wi Fi or compatibles, digital inputs for the interface of pulse output sensors.

It would be advantageous to provide a meter focused on the administration of power.

DESCRIPTION OF THE PREFERRED EMBODIMENT

FIG. 1 shows the complete schematic diagram of the Triphase Multifunction Verifier 6. The design of the Triphase Multifunction Verifier 6 centers on a processing unit based on a RISK type micro-controller 1 with a 16 bit nucleus with a 50 MHz operating frequency. The micro-controller 1 has 3 SCI 14 ports, an SPI 22 port, an I2C 15 port, a 16 bit port for keyboard 3 and external interrupts, 16 bit general purpose 25 port with option for interruption trigger, 16 bit general purpose 25 port, 6 channels of pulse width modulation (PWM), 4 channel timers, two digital to analog converters, a 6 channel analog to digital converter, configurable watchdog timer, 128 K of Flash EEPROM and 8K of RAM.

The user interface module 24 includes interconnections of up to 16 keys cabled directly to the port available for the keyboard 3, wired connections from the general purpose 25 port towards a connection for an LCD 2 display of 8 bits connecting the signals of display control to three additional bits of the same port.

FIG. 2 shows the communication module which includes the circuitry to connect one of the SCI 14 ports to optical couplers for its connection by means of an optical probe 28 being using an infrared diode and a phototransistor with its respective polarization resistance and a transistor like switchboard to receive and establish the digital thresholds of the phototransistor (ANSI C12. 18 type optical port 8). Another of the SCI 14 channels is connected to a standard transceiver 13 for a 3 volt RS 485 BUS 10 to which is included minimum circuitry and a connector with a receiver for its connection to an RS 485 network 26. The additional SCI 14 port is interconnected directly to an external receiver for an in series direct connection by means of TTL signals, useful to provide transparent communication with serial circuits adapters to another media type and to obtain with this its connection to a remote module (remote communication 7).

A specialized of realtime clock 16 (RTC) circuit of high precision with quartz crystal including an internal real time clock generator is added. At the same time it includes backup energy circuitry with a 3.3 volt battery 17 utilizing an internal switchboard which detects energy failures. The real time circuit communicates with the micro-controller 1 through the I2C 15 port using simple serial commands and readings from the realtime clock 16 (RTC) internal time registry.

An energy failure detection module is included using a specialized integrated circuit supervisor 18 which is in charge of providing an unmaskable interruption to the micro-controller 1 and using a capacitor of great capacity provides backup power with sufficient back-up energy as to provide the opportunity to store the essential information for the function, in addition this circuit provides an external watchdog timer which is required to be take care of by a general purpose 25 line of one of the ports to avoid it from realizing a reset since it is connected directly to the micro-controller's general reset terminal. The two elements described above (RTC, supervisor 18) make up a backup module 5 that guarantees the correct operation of the equipment even though there is a power failure.

By means of three general purpose 25 lines shown in FIG. 4, and up to 4 additional lines of the same type an SPI 22 channel of emulation for communication with integrated circuits of serial flash 20 memory is established as seen in FIG. 3. The first two lines emulate the inherent SPI 22 signal lines and the additional ones are used for selection as the slave (CS 21 memory) with which communication is required. This emulated SPI 22 connects to the memory bus having for its operation a memory bank 4 resulting from the sum of the capacities of each individual memory. This memory bank 4 is used to store the periodic historical data and provides the functionality with external not-volatile registry of data. The circuitry is required for the operation of the memory and is added strictly speaking.

FIG. 3 also shows the input and output real time clock signal lines of CK which are CKI 30 and CKO 31 respectively. CKI 30 and CKO 31 are real time clock clock signals. Normally the digital circuits need a signal that provides clock pulses for its operation, this signal commonly is known as CK, the signal CKI 30 signals are the real time clock signals input to the verifier's specialized measurement circuits, the first of directly takes the signal for CKI 30 from the quartz crystal. In the diagram, CKO 31 are the output real time clock signals of the integrated circuits that appear in the same circuit. The first two measurement circuits of verifier pass along pass along their real time clock signal by means of CKO 31 and the circuit that receives this signal captures it by CKI 30. In this manner, the third set of circuits only receives signals from CKI 30 but it does not use CKO 31 whereas both of the previous circuits use CKI 30 signal lines.

FIG. 4 shows the resistive and transistorized couplers for the connection of 4 entrances originating from pulses equivalent to the measurement of some cumulative variable are included, allowing with this the interaction with digital output devices or collectors or open sources without distinction. These entrances interconnect with general purpose 25 lines with associated interruption and the possibility of external connection with the micro-controller's timer channels. General purpose 25 digital output lines are prepared in addition towards external connectors for the possible control of relays, actuators or external load control modules.

The tri-phase electrical parameters measurement module (tri-phase measurement machine) is based on an integrated circuit of specific intention for the monitoring of analogical inputs connected with alternating current and voltage, direct or composed. The measurement machine is made up of a tri-phase adjustment that uses three circuits mentioned before and providing the real time clock circuitry necessary for its operation by means of a quartz crystal and capacitive elements to later share its real time clock signal with the remaining two circuits and in this manner to assure synchronicity for the measurements. In addition, to each circuit is added additional elements of high precision for polarization and connection of signals and is equipped with the necessary control lines for the calibration of the equipment. The communication of the micro-controller 1 with this measurement machine is realized through an SPI 22 bus and using additional lines for the selection of the slave, the measurement circuits provide their information in the form of registry and with pulse energy signals connected to the micro-controller's interruption inputs and an optical coupling port to realize the calibration and precision 23 tests.

Additionally, circuitry required for the operation of the micro-controller 1 is provided e.g.: capacitive elements, quartz crystal and elements of protection against discharges of static electricity and short circuit. In addition, a feeding module with a converter of CD to CD is included and takes a voltage from CD from an externally connected source and converts it and regulates to provide the necessary feeding voltages for integrated circuits and peripherals (5 and 3 volts).

An external communications power module on which is annexed direct connections for measurement of electrical phases and inputs of pulses are realized, this module, includes the necessary protections from overvoltage, over current and short circuit, connecting itself through a connector with receiver terminals (fingered) or through a flat cable connector with connection to a strip of terminals of the main board.

The terminal connector at the edge of the main card (edge connector 11) includes all the signals of measurement and communications with the outside and in addition allows its connection with multi-point measurement systems by measuring card insertion of the same type under the philosophy of Hot Swap.

Since other modifications and changes varied to fit particular operating requirements and environments will be apparent to those skilled in the art, the invention is not considered limited to the example chosen for purposes of disclosure, and covers all changes and modifications which do not constitute departures from the true spirit and scope of this invention.

Having thus described the invention, what is desired to be protected by Letters Patent is presented in the subsequently appended claims.
